The doc states:

If a specific tool cannot handle the standard comment style, then the
appropriate comment mechanism which the tool accepts shall be used. This
is the reason for having the "/\* \*/" style comment in C header
files.

I interpreted that as dtc doesn't handle // comments, use /**/

But I agree it also states:
.dts{i}:	  // SPDX-License-Identifier: <SPDX License Expression>

So I think we will end up with a mix of both.
